WORLD HISTORY

Detailed explanation-1: -Realists consider the principal actors in the international arena to be states, which are concerned with their own security, act in pursuit of their own national interests, and struggle for power.

Detailed explanation-2: -Realists believe that sovereign states are the principal actors in the international system. International institutions, non-governmental organizations, multinational corporations, individuals and other sub-state or trans-state actors are viewed as having little independent influence.

Detailed explanation-3: -The first assumption of realism is that the nation-state (usually abbreviated to ‘state’) is the principle actor in international relations. Other bodies exist, such as individuals and organisations, but their power is limited.

Detailed explanation-4: -Realism (including neorealism) focuses on abiding patterns of interaction in an international system lacking a centralized political authority. That condition of anarchy means that the logic of international politics often differs from that of domestic politics, which is regulated by a sovereign power.

Detailed explanation-5: -Hans Morgenthau is considered one of the “founding fathers” of the realist school in the 20th century. This school of thought holds that nation-states are the main actors in international relations and that the main concern of the field is the study of power.
